Harnessing the Leftover Power of Used Hydroprocessing Catalysts
Evonik, a global leader in the catalyst and adsorbents industry, is revolutionising the refining sector with its innovative and sustainable approach to managing spent hydroprocessing catalyst definition.
Every year, refineries worldwide generate thousands of tons of spent hydroprocessing catalyst meaning. Traditionally, a large portion of these catalysts have been treated for metal reclamation or landfilled, presenting a missed opportunity for sustainability. However, Evonik's catalyst acquisition program transforms these spent catalysts into an asset.
Hydroprocessing units, such as hydrotreaters and hydrocrackers, rely on high-performance catalysts to remove impurities from petroleum streams. These catalysts are rich in valuable metals critical to catalyst performance, and their sourcing through traditional mining comes at a high environmental and economic cost.
Evonik's catalyst acquisition program assesses the full reuse potential of spent hydroprocessing catalysts, tailoring approaches to maximise value extraction, and simplifying logistics and compliance. Each container of spent catalysts is sampled, sorted, and screened by Evonik to determine the best way forward for reuse.
The program offers a unique tiered pricing system that rewards customers based on the composition and condition of their spent materials. The recovery of molybdenum (Mo), cobalt (Co), and nickel (Ni) can range from 20-75%. The repurposing process also results in a significant cut in raw material demand and delivers a 60% reduction in waste and CO2 equivalent emissions.
Repurposing spent hydroprocessing catalysts is a smarter alternative, offering benefits such as avoiding environmental costs associated with mining virgin metals, reducing hazardous waste generation, and minimising CO2 emissions. Evonik's approach helps refiners reduce waste, reclaim value, and improve environmental performance.
Through its catalyst acquisition program, Evonik has kept more than 113,000 tons of spent catalysts out of landfill to date. The program supports a circular catalyst lifecycle by recovering reusable metals, enabling regeneration, and diverting material from landfill.
Excel Rejuvenation Technology, a key part of Evonik's offering, restores catalytic activity to near-fresh levels, offering substantial sustainability and cost benefits.
Dr. Michael Riecke and Dr. Thomas Schwarz, the managing directors for Hydroprocessing at Evonik, lead this groundbreaking initiative. Evonik Catalysts has been a leader in the industry for over 75 years, and this program is a testament to its commitment to sustainability and innovation.
In conclusion, Evonik's catalyst acquisition program is a game-changer for the refining industry, offering a sustainable, cost-effective, and environmentally friendly solution for managing spent hydroprocessing catalysts. By repurposing these catalysts, Evonik is not only helping refiners reduce waste and improve their environmental performance but also contributing to a more sustainable future.
